Study Notes
Computer Systems Overview
- Basic Structure: Consists of core components including CPU, motherboard, and power supply within a protective case.
- Peripherals: Devices connecting to the core unit, enhancing functionality, such as monitors, keyboards, and storage devices.
Computer Associated Peripherals
- Definition: Any device not integral to the core architecture but connects to it, enabling additional tasks.
-
Examples:
- Mouse and Keyboard: Input devices for user interaction.
- Monitor: Displays visual output.
- Printer: Produces hard copies of digital documents.
- RAM and DVD-ROM: Storage devices aiding in memory and data retrieval.
Memory Classification
-
Primary Memory:
- Random Access Memory (RAM): Volatile memory used for temporary data storage; categorized into SRAM and DRAM. Data is lost when power is off.
- Read-Only Memory (ROM): Non-volatile memory that retains data; used for essential programs like system boot processes. Types include MROM, PROM, EPROM, EEPROM.
Secondary Storage Devices
- Definition: Non-volatile storage enabling permanent data retention beyond primary storage (RAM).
-
Examples:
- Solid-State Drives (SSDs), Hard Disk Drives (HDDs), CD/DVD/Blu-ray drives, USB flash drives, and cloud services (e.g., Google Drive, AWS).
- Purpose: Used for backups, archiving long-term data, and storing non-critical information.
System Configuration
- Definition: Describes the hardware, software, and processes comprising a computer system, along with their interactions.
- Components: Includes specific devices, operating system settings, and software in use.
Programming Languages
- Machine Language: The fundamental language understood by computers; offers direct control but is tedious for humans.
- Assembly Language: Low-level programming language closely aligned with machine code, requiring an assembler to translate into executable code.
- High-Level Languages (HLL): Such as C, FORTRAN, and Pascal, which are more accessible for programmers and abstract away hardware specifics.
Development Workflow
- Users write programs in high-level languages.
- Compilers convert these programs into assembly language.
- Assemblers translate assembly language into machine code, completing the programming cycle.
